New dietary guidelines

Every five years, the USDA and HHS update the dietary guidelines that form the basis of U.S. nutritional policy. The new 2010 guidelines, more than ever before, focus on scientific evidence as distilled from last summer's advice from an expert advisory panel.

The new dietary guidelines focus on two major themes:

• watching calories to achieve and maintain a healthy weight
• tipping the balance of calorie intake: More calories from nutrition-rich foods, fewer calories from solid fats, sugars, and refined grains
